48-CCV 4L80E Converter Conversion Kit
Important: This kit cannot be used with a computer that allows lockup. This kit corrects converter fill and lube flow, for performance when using a non-lockup converter. It can not be used with a converter that has a lock-up plate!
Step 1
Install new RED inner spring on Converter Limit Valve. Then Re-install the
original spring, end plug, and retainer.
Step 2
Grind the stem off the long stem end of the TCC enable valve. Re-install the
original spring and then the end of the valve that was ground off.
Step 3
Discard the original lock-up valve and spring. Install New valve and original
end plug and retainer.
Step 4
Install the plugs furnished, just below flush, into these two holes.
Note: This kit has the flow and the pressure necessary to keep the
converter full under heavy load or high HP use.
Without this kit, the converter will tend to empty of fluid under high load
conditions.
